i recently purchased the above knife in D2 steel. i had thought that a razor blade was a chisel grind (i.e. sharpened on one side only). however i am probably wrong as this knife is sharpened on both sides. what angles and polish level should i strive for if i wish to shave with this knife. or, is that not what this blade is intended for ? also, having never used a straight razor in all my 60 years, i would appreciate any advise on technique. thanks, roland
